This list will be added to on a regular basis. The list is ordered by seriousness: Work stuff at the top, play stuff at the bottom.
Unless stated, these are all freebies.

www.logmein.com for free remote controlling software.
Install it once on a client's machine (make sure you choose the free version) and you can get access to that machine from anywhere on the web.

www.transferbigfiles.com for - you guessed it - transferring big files. It's a freebie and works for sending anything up to a gigabyte in size!

www.dabbleboard.com for freehand drawing with the mouse. It interprets your rough scrawling and turns your circles into circles, etc.

www.freebyte.com Check out lots of freebies, including Freebyte Backup (under File and Disk Utilities). I use this one alot!

www.flightview.com Great flight arrivals/departure web page. Shows you an animation of where the flight is, in real-time.
